It has been found in many cells that ribosomes occur in chains along $mRNA$ molecules. What is the advantage of this arrangement as compared to a situation in which ribosomes occur singly?

Read the following statements and choose the correct set of statements:
$(a)$ $\text{tRNA}$ has an anticodon loop that has bases complementary to the code.
$(b)$ The $\text{tRNA}$,also called $\text{sRNA}$,was known before the genetic code was postulated.
$(c)$ For termination codon,there is a specific $\text{tRNA}$ that is referred to as terminator $\text{tRNA}$.
$(d)$ The secondary structure of $\text{tRNA}$ has been depicted that looks like an inverted $L$.
Choose the correct answer from the options given below:

During translation,proteins are synthesized by

During translation,in which direction does the ribosome move along the $m-RNA$ and by how much?

Identify the correct sequence of events involved in the synthesis of a polypeptide during translation.

$t-RNA$ constitutes about
